Write and run (using appropriate calling program) a near procedure in 8086 assembly language that converts 2 ASCII digits stored in two registers (say BH and BL) into an equivalent binary number. For example, if the BH and BL registers contain digits 4 and 5 respectively, then the binary number obtained will be 0010 1101 which is 45 in decimal. The parameters should be passed using registers and the result should be returned in AL register – IGNOU MCA Assignment 2016 – 17

Write and run an Assembly language program that converts lowercase alphabets in a given input string to uppercase. The input may consist of uppercase alphabets, special characters and lowercase alphabets. For example, for the input string A@abAYaf, the output will be A@ABAYAF.
